If you enjoy a satisfying game, get this. One of the best ways to describe this game is; solely satisfying. The game visuals, atmosphere, ambientsounds, overall gameplay is satisfying, this game seems to convey a great sense of joy with the weapon sounds firing, realistic weapon mechanical movement and shell ejection in slow motion as you pump a full meatshot into an ugly shambling freak's squishy head as it explodes into a shower of blood, releasing the bone snapping and meat curling sound that is a headshot in slow motion. Thank "Insert personal religious deity affiliation here" there is a horde of more of them right behind the first victim, you still have an almost full clip, teammates got your back like a buttcrack, and the continuous slow motion only feeds your cooperative psychopathic rampage entitled: "Killing Floor."

Post-apocalyptic setting, run down abandoned ghost towns, soviet bunkers, dark insidious laboratories, freak experimentations, mutants, zombies, aliens, spectres, electric disturbances, nuclear fallout, radiation, gravity fields, spontaneous fire streams, acid pools, anomalies, artifacts, super powers, fire fights, factions, soldiers, looters, bandits, murder, stealth, treachery, survival and lovingly wrapped with amazing atmosphere, slow enjoyable pace and sprinkled with an ominous omnipresent sense of mystery...
This game has it ALL.
The story and setting make it all believable in this parallel universe; which is not so far from our own...

It gets repetitive.
REAL fast.
do not buy it.
I might change my mind if they release new FREE dlc.
